Börn Loka is ostensibly about Viking outcast Hilmar Baldursson and his sister Brynhildur, and follows Hilmar's quest to provide for his sister by fighting Loki's three famous children, but it's really about Loki taking out his revenge on Baldur's children.

A little more knowledge of the Eddas (particularly who Narfi and Váli are, and what happened to them) is needed to really understand Loki's motivation or Brynhildur's fate.

The three eponymous monsters are each sung in a different vocal style: the wolf Fenris Úlfur screams a black metal scream, the Miðgarð Serpent Jörmundgandur is sung in a traditional Icelandic rimur style, and Hel, the goddess of death, is sung with a second death metal growl from guest vocalist Edda Tegeder of Angist.

Frontman Björgvin Sigurðsson narrates Hilmar's story and provides the voice of the god.

The main character, Hilmar, was named after the son of the band's lead singer and guitarist Björgvin Sigurðsson, while his sister Brynhildur is named after Guitarist Þráinn Árni Baldvinsson's mother.
